The Desert Waits is a 99 cent book that's worth much more than I paid. This is a good murder mystery with some interesting twists.
Alex gets a message from her old friend Caroline to come to the desert because she's needed. When Alex gets there she finds her friend in a strange mood and threatened by a stalker. Then Caroline is killed and the mystery deepens. This story has some great descriptions of the desert and the animals who inhabit it, in addition to plenty of murders and bad guys. Highly recommended.
